My invention relatesvto' theformationof joints is of` service' in many. structures. Lhave actually emb'odife1d? `myinvention in supports for sca-le pans, suchf'anf embodiment ofthe invention includingy a lill-shaped scale 'panir carrying membery or, support; formedigof strip metailland` eurvedy atfits endsin transverse directions to makethe supportconcave 4upon -the.; inner/opposing faces thereof and .convexon theouter `faces i thereof.;4 second i -constitutes a strut'between the sidesof the I lshapedsupport, this second strip hav- Aingjay projection atn each end'. received in'the ad]- acent cavityof? the support. to which such .projection conforms in shape. LThe second strip. alsofhas herns on: each sideofv each endprojection, these horns enteringL notches `that areformed in thejedgeportins o fthe curved parts of the." support.. These horns are inwardly curled, or bent over the convex surface of;` the.;A support whereby .Y the` i str-ut andV supportare clinched. together.

'Y'IhefsufpportV also constitutes), a positioner foritheseale pan, the latter elementbeing ,formedA with. ridges fitting the convex` Ysides of.V the support.: Holesy are formedfincithe scale panand, strut at the endsfofthe strut and within the ridges. andconcave sides of the support, these holes receiving screws o r othery fastening. members whereby :the scale pan` is assembled with the support andthe 'strut. l/Vhile the supportY is preferably .curved fatitsf ends to make the opposing faces thereof.'v concave and. the outer `faces thereofconvexa do not wishto bejlimitfed to/the; employment* offcurves. as thereside edgesof thesupport mayv be otherwiseflared torealize the object-of my. invention; l

Vliile Ihaveherein shown andkv particiiy larly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention but having thus described my invention I claim as new and desire to secure by Letters Patent the following 1. A joint including a strip bent in a transverse direction to be concave on one side and convex on the other and having opposite notches, one at each edge; a second strip having a projection at one end received in the cavity of the first to which this projection conforms in shape, the second strip also having horns, one on each side of its said projection, which enter the notches in the first strip and are inwardly bent over the convex face of the first strip; a plate having f a hole therein in register with a hole that is formed at the projection in the second strip, the plate being formed with a ridge lshaped to fit the convex side of the first strip; and an assembling member in said f holes and in holding relation to the strips.

2. A joint including a strip bent in a transverse direction to be concave on one side and convex on the other and having opposite notches, one at each edge; a second strip having a projection at one end received in the cavity of the first to which this projection conforms in shape, the second strip also having horns, one on each side of its said projection, which enter the notches in the first strip and are inwardly bent over the convex face of the first strip; and a plate having a hole therein in register with a hole that is formed at the projection in the second strip, the plate being formed with a. ridge shaped to fit the convex side of the first strip.

3. A joint including a strip bent in a transverse direction to be concave on one side and convex on the other and having opposite notches, one at each edge; a second strip having horns, one on each side, which enter the notches in the first strip and are inwardly bent over the convex face of the first strip; a plate having a hole therein in register with a hole that is formed in the second strip, the plate being formed with a ridge shaped to fit the convex side of the first strip; and an assembling member in said holes and in holding relation to the strips.

4t. A joint including a strip bent in a transverse direction to be concave on one side and convex on the other and having opposite notches, one at each edge; a second strip having horns, one on each side, which enter the notches in the first strip and are inwardly bent over the convex face of the first strip; and a plate having a hole therein in register with a hole that is formed in the second strip, the plate being formed with a ridge shaped to lit the convex side of the first strip.

5. A joint including a strip bent in a transverse direction to be concave on one side and convex on the other and having opposite notches, one at each edge; a second strip having a projection at one end received in the cavity of the first to which this projection conforms in shape, the second strip also having horns, one on each side of its said projection, which enter the notches in the first strip and are inwardly bent over the convex face of the first strip; a plate having a hole therein in register with a hole that is formed at the projection in the second strip, the plate being formed with a ridge fitting the end of the first strip; and an assembling member in said holes and in holding relation to the strips.

6. A joint including a strip bent in a transverse direction to be concave on one side and convex on the other and having opposite notches, one at each edge; a second strip having a projection at one end received in the cavity of the first to which this projection conforms in shape, the second strip also having horns, one on each side of its said projection, which enter the notches in the first strip and are inwardly bent over the convex face of the first strip; and a plate having a hole therein in register with a hole that is formed at the projection in the second strip, the plate being formed with a ridge fitting the end'of the first strip.

V7. A joint including a strip bent in a transverse direction to be concave on one side and convex on the other and having opposite notches, one at each edge; a second strip having horns, one on each side, which enter the notches in the first strip and are inwardly bent over the convex face of the first strip; a plate having a hole therein in register with a hole that is formed in the second strip, the plate being formed with a ridge fitting the end of the first strip; and an assembling member in said holes and in holding relation to the strips.

8. A joint including a strip bent in a transverse direction to be concave on one side and convex on the other and having opposite notches, one at each edge; a second strip having horns, one on each side, which enter the notches in the first strip and are inwardly bent over the convex face of the first strip; and a plate having a hole therein in register with a hole that is formed in the second strip, the plate being formed with a ridge fitting the end of the first strip.

9. A joint including a strip bent in a transverse direction t-o be concave on one side and convex on the other; a second strip having a projection at one end received in the cavity of the first to which this pro- Sii jection conforms in shape; and a plate assembled with said strips and having a ridge fitting the convex side of the first stripY 10. A joint including a strip bent in a 5 transverse direction to be concave on one l side and convex on the other; a second strip abutting the concave side of the first; and

a. plate assembled With seid strips and having a ridge iitting the convex side of the first strip. i

In Witness whereof, I hereuntosubscribe my name this 13th day o'J une, A. D. 1923.
